Lit Essay: Thematic Quote HELP!!

My English class is having us write an essay. The essay needs to focus on a specific passage in Huck Finn that has thematic importance and is 100-200 words long. We also need to provide evidence and analysis that focus on: author's language choices [denotation, connotation], syntax, sentence structure, structure of passage, irony, satire, parody, narrative point of view, symbolism, metaphor, imagery, any other elements of form or style that helps develop theme.
Any good ideas on which passage to use? Please post ASAP!
Thank you!
